Application filed March 19, 1925. Serial No. 16,682.v

'lhe object of the present invention to provide an electric coin control mechanism of a type in which the coin actuates a switch for closing an electric circuit or ycircuits leading to operating means for a train or trains of mechanism and in which the com slot is automatically closed Aand opened at predetermined times. The invention is particularly applicable to my automatic photom graph apparatus forming the subject or' certain copending applications filed by me.

The invention will be understood by reiference to the accompanying drawings, in which- Figure 1 is a sectional view in elevation oi' the coin slot closing mechanism, snowing' the slot open; V

Referring to Figure 1 of the drawings, 1

represents a framework in which is formed the coin slot 2, the latter communicating with a coin chute 3 which will be suitably supported by framework 1. Above the hori- Zonal member ot the fran'ieworlr is a plate 8', having a coin passage 2', and movable horizontally below plate 3 is slot closing plate d. y

rlhe plate 8 is vj novided with a Vdownwardly extending flange aiiording a shoulder against which presses a spring 5 and slot closing plate at that end extending toward the coin slot is reduced iu thickness thus altording a space for the reception oi and a shoulder for engagement by the spring 5. This spring serves to normally maintain the slot closing plate to the right and out ot register with the Vslot. The said plate is guided at its side edges by the walls ot removable bars The slot'closiug plate is directly operated by a cam 7 which is shown in plan view in Figure 7. The cam in this instance formed as a rectangular bloclcand it is given uni-'directional intermittent motion through its carrying shaft 8. Shaft 8 rotates in a bushing 9, and below said bushing it carries a pin 10. A ratchet 11, formed as a sleeve and with bevelled ratchet teeth 11 on its upper annular surface, i mounted on shaft 8, in such manner that ratchet teeth 11X engage pin 10.

Ratchet sleeve 11 is longitudinally movable on shaft 8 and it is spring-pressed yupwardly into engagement with pin by a spring 12. The sleeve is provided with a laterally projecting arm 13 connected by cable 14 with core-rod 15 actuated by magnet 16. Bod 15 is normally maintained in outer position,` as shown in Figure 1, by a spring 15X. The ratchet sleeve 11 is also provided with a short arm 13X engaged by a coiled spring 17 which serves to return the sleeve to its position as shown in Figure 1, after each operative movement. Coin chute 3 is formed at its sides with the flanged and inturned walls 8X which serve to hold t-he coin against `displacement in its downward movement.

- Near the lbase of the'coin chute the latter is covered by a coin Vrelease plate 18, the latter being pivoted at 19 upon support 20; Coin release plate 18 is spaced from support 20 a distancesomewhat greater than the .thickness of the coin, andV nit 'is also formed with a guide-wall 18X, the whole forming a passageway for the .coin which passageway is closed on three-sides, and which passageway is a continuation of the coin chute.

Secured at 21X upon support 20 is a flatspring 21 which is normally inclined toward the inclined open face 18XX of coin release plate 18, as shown in full lines Figure 2.

When a coin passes downwardlyinto the continuation'of the coin chute, itis checked in the position A, Figure 2, although in its passage to such position it has, by its weight rand pressure, moved flat spring 21 to its dotted line position as shown in said ligure,

At its lower end 'flat spring 21 carries a Contact 22 to which current is led via the flat spring fromany suitable connection as that shown at 23, for example. The fiat spring is insulated from the coin and coin release plate by suitable insulation, part of this insulation lieing indi-cated at 24. lli/Then desii-ed the support 20 itself may be made of non-conducting material.

On support 20 and suitably insulated from l'lat spring 21 is a contact member 25 having a contact face 25X and having a connection, such as 26, in the same circuit as connection 23, which circuit is normally brokenl by the separation of contacts 22 and 25X. In the said circuit also, are the connections 27 of magnet 16.

lVhen the coin moves to position A and brings contacts 22, 25X together, the circuit is closed through magnet 16, core-rod is drawn inwardly thereby carrying ratchet sleeve to the positionshown iirFigure (i, its teeth 11X acting to impart a quarter turn to cam 7, the latter moving coin closing plate to` closed position, as shown in said ligure. The closing of the circuit will also throw into action devices to which the coin control is applied, as for example my automatic photographie machine. It will: be assumed for the purposes of the present application that a moving member of the said devices will, Vin a given interval of time, throw a switch which will close a circuit leading to the connections 28X of a solenoid 28 which is arranged to operate the coin-release plate 18.

Solenoid 28 is provided: with a field plate 29'normally held open by a spring 30 on a rod 31, which vlatter connects the lield plate with the coin-release plate 118. At one end spring 30 bears against a wall 32X of a bracket 82 which serves to support the solenoid and to guide rod 31 in its movements. The immediate connection betweenV rod 31 and coin-release plate 18V is a stud 38 which passes through a slot in the said plate,` thus allowing a small relative movement between the rod and theA plate to compensate for the pivotal or lswinging movementof the latter. In the operation of the solenoid 28, plate 29 will initially be drawn to the left from its position shownin Figure 2, carrying with it rod 31, and the latter will act to swing coinrelease plate on its pivotal connection 19. The coin will then be released. The circuit to solenoid 28 is to be closed only for an nstant, and, when broken, spring 30 will return the plate 29 and rod 31 to initial po-V It will be understood that various modifications may be made inthe form and arrangement of the elements illustrated in Ythe drawings without departing from the spirit of the, invention, what I claim and desire to secure by Letters Patent being as follows lnelectrical coin control mechanism, a frame, a coin passageway, a coin release platepivoted 'on' said frame and having an open side, the plate being of gradually decreased width toward' its discharge end, a spring arm adjacent said open side, the plate and the arm being adapted to hold a coin between them after the coin has by its weight imparted a movement to the arm, a switch element on the arm, a second switch element in the path of movement of the arm, for nory k.mally holdingv the. coin release Vplate in; a given position, a solenoid, and means operatively connecting release plate.

the solenoid and the coin l In testimony whereof, have vsigned my l name to this specification.
